Intracranial cavernous angioma. Report of two cases in the same family.

: We report two cases of intracranial cavernous angioma in members of one family and discuss our clinical and surgical findings in a further 10 cases of this lesion seen in the past five years. We stress the value of RNM, which supplies a precise diagnosis of nature, site and size, especially when the lesion is surrounded by a recent hematoma. NMR is especially indicated in suspected familial cavernous angioma, as in the cases reported.
